Free Online Tone Generator
↑The MP3-AI.com Tone Generator creates pure audio tones using the Web Audio API OscillatorNode. You can generate tones at any frequency from 20 Hz to 20,000 Hz — the full range of human hearing — using four different waveform types: sine, square, sawtooth, and triangle. Each waveform produces a distinct timbre, from the smooth pure tone of a sine wave to the rich harmonics of a sawtooth wave.
Sine waves produce a pure, fundamental tone with no harmonics, making them ideal for hearing tests, tuning instruments, and scientific applications. Square waves contain odd harmonics and produce a hollow, buzzy sound similar to early video game audio. Sawtooth waves contain both even and odd harmonics, creating a bright, buzzy tone often used in synthesizers. Triangle waves are similar to sine waves but with a slightly brighter character.
The tone generator includes convenient preset frequencies for common musical notes including A4 (440 Hz, the standard tuning reference), Middle C (261.63 Hz), and E4 (329.63 Hz). Additional presets cover bass frequencies at 100 Hz, treble at 2000 Hz, and sub-bass at 40 Hz. The volume control lets you adjust the output level from silent to full volume for comfortable listening.
This tool is essential for musicians tuning instruments, audio engineers testing speaker response, students learning about acoustics, and anyone exploring the properties of sound waves. All tone generation happens in real time using your browser's audio capabilities. The interactive frequency slider provides instant feedback as you sweep across the audible spectrum, letting you hear how different frequencies sound and feel.
